A well-known, old ‘verbena’ variety with toothed, dark green leaves and flat clusters of bright magenta-pink flowers from late spring into autumn. ‘Sissinghurst’ is a spreading semi-evergreen perennial perfect for spilling from patio pots, windowboxes and large baskets.
Grow on under glass until all risk of frost has passed and they can then either be planted outside into a well-prepared bed, or used to fill decorative pots and hanging baskets for the patio. Pinching out the growing tips will encourage them to become bushier, and feeding with a high-potash fertiliser at regular intervals throughout the summer will promote even more flowers to form.
